By default, the system recognizes equivalent algebraic, numeric, equation, and unit expressions in student responses. This behavior is controlled by your instructor in the event that the learning objective of a particular question is for you to demonstrate an understanding of the equivalent expression.
If the answer to a question is (t+1)2, a response of (t+1)2 or (t2 + 2t + 1) is graded correct.
10000 cm2 is equivalent to 1 m2.
Important: Read your question instructions carefully and be sure to enter an appropriate response. For instance, if the question asks you to reduce an algebraic expression, it would be inappropriate (and graded wrong) to enter the source expression. |
